U.S. Bankruptcy Court Assumes Jurisdiction

             in Enron, Sierra Pacific Resources' Dispute 
  LAS VEGAS, Dec. 2 /PRNewswire-FirstCall/ -- Sierra Pacific Resources
(NYSE: SRP) said that the U.S. Bankruptcy Court for the Southern District of
New York today enjoined the company's electric utilities from participating in
Federal Energy Regulatory Commission (FERC) hearings that were scheduled to
begin December 13, 2004, in the companies' ongoing dispute with Enron Power
Marketing, Inc. over terminated power contracts. 
Judge Arthur Gonzalez, who said he will issue his final order Friday,
December 3, stated that the issues involved in the proposed FERC hearings were
"duplicative" of what is now before his court. 
On October 11, 2004, the U.S. District Court for the Southern District of
New York had vacated a prior summary judgment by the Bankruptcy Court calling
for the Sierra Pacific utilities to pay Enron a total of approximately
$336 million for terminated contracts.  The court remanded the case back to
Judge Gonzalez to rehear facts, issues and arguments of the case. 
Sierra Pacific Resources said it is reviewing its options, which include a
possible appeal of today's decision. 
  Sierra Pacific Resources is a holding company whose principal subsidiaries
are Nevada Power Company, the electric utility for most of southern Nevada,
and Sierra Pacific Power Company, the electric utility for most of northern
Nevada and the Lake Tahoe area of California.  Sierra Pacific Power Company
also distributes natural gas in the Reno-Sparks area of northern Nevada.
Other subsidiaries include the Tuscarora Gas Pipeline Company, which owns a
50 percent interest in an interstate natural gas transmission partnership.
